Some believe that it doesn’t matter much what happens during any implementation period to an EU deal. What matters is happens after it – in other words, that Britain is completely out of the EU de facto as well as de jure at that later point.

This is not a view that most Party members share, if our survey is correct.

Support for the reduction of EU migration during any implementation is relatively low (i.e: just under half the returns), while backing for Britain being able to negotiate and sign trade deals is extremely high (nearly nine out of ten members favour it).

Also note that about two in three party members want Britain out of ECJ jurisdiction during such a period.

Finally, there is a certain hesitancy about opting either to follow the EU’s economic model or to diverge from it, either during any implementation or after it.
